"We are working around the clock to fortify not just the four buildings that were damaged during the course of the November riot, but in fact we are going to be fortifying each and every one of the buildings at the Parkville facility.

"We have some serious shortcomings, the Parkville facility is clearly not fit for purpose, the infrastructure limitations have become very apparent."

In November, inmates at the facility destroyed security cameras and trashed ceilings and walls, causing about $2 million in damage.
